(o1. iss-183) "2 Claims.

This invention `relates `to governors `and more particularly a hydraulic governor.

The primary object of this invention resides inthe provision of a hydraulic governor adapted to control the speed of windmills so as to maintain uniform transmission of power therefrom to electric generators, machinery and the like.

Another object of this invention resides in the provision of a hydraulic governor having a particularly constructed valve mechanism adapted to be actuated by the speed of a driven shaft so as to maintain uniform rotation thereof.

A further object of this invention resides in the particular construction of the rotating governor.

A still further object of this invention resides in the particular construction of the rotating governor and associated adjuncts thereof.

Aside from the aforesaid objects is the particular driving means for the governor.V

With these and other objects in View this invention resides in certain novel features of construction and arrangement of elements to be hereinafter fully set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claims and, while this disclosure depicts my present conception of the invention, the right is reserved to resort to such changes in construction and arrangement of elements as come within the scope of the claims.

In the accompanying drawings forming a part of this application:

Fig. 1 is a front view of the upper portion of a conventional windmill showing this invention operatively associated with the rotating drive shaft thereof, the blades being shown in dotted lines.

Fig. 2 is a side view thereof.

Fig 3 is an enlarged sectional View through the hydraulic governor with the valve in open position.

Fig. 4 is a detail side View of the rotating governor shaft showing the rotating means therefor.

In the present illustration of this invention the letter A designates, in general, the upper portion of a conventional windmill which, among other necessary adjuncts, consists of a rotatable base 5 carrying a drive shaft G supporting blades 1.

Suitably secured on the base 5 is a liquid or oil reservoir 8 communicating with a casing 9 at its bottom through the instrumentality of a conduit IU.

end,"said'chambe`r being provided With 'a bevelled valve-seat I3 at its bottom and connected in communication thereabove with the top of the casing 9 through the instrumentality of a conduit I4.

Rotatably mounted on the free end of the chamber I2 as by an apertured nut I5 or other suitable means is a tubular shaft I6 having a bevel-gear II suitably secured thereto adapted to mesh with a similar bevel-gear I8 journalled on a stud I9 extending from the outer periphery of the chamber, said bevel-gear I8, while herein shown as being provided with a V-shape pulley I8', may be formed with a sprocket or other suitable gear.

Extending through aligned slots 20 in the tubular shaft I6 is a cross-head 2| connected to a valve 22, operable within the valve-chamber I2, through the instrumentality of an elongated stem 23, said cross-head in turn is operably connected to centrifugally controlled arms 24 pivoted as at 25 to the tubular shaft and held in their innermost position by springs 26 or other suitable elements.

Disposed in the casing 9 and keyed to the shaft 6 is one gear of a gear-pump 21 adapted to cause the liquid or oil in the reservoir and communicating adjuncts thereof to flow freely there.- through when the valve 22 is open and retarded as the valve is closed by the centrifugal governor which is operated through the instrumentality of a pulley 28 on the shaft E connected by a belt 29 or' the like to the aforesaid pulley I8', thus it will be readily observed the speed of the shaft 6 will be controlled by manipulation of the Valve and uniform operation of the windmill maintained.

While this invention is herein disclosed as being practiced with a windmill it is to be understood the same may be associated with other types of machinery or the like to maintain uniform or smooth operation of its power transmitting shaft.

With this invention fully set forth it is manifest that means have been produced whereby uniform rotation of power transmitting shafts will be maintained and, through the simplicity of construction thereof, connection of the same to conventional machinery and the like can be made with the minimum degree of labor with positive operation assured.

Having thus described my invention what I claim and'desire to protect by Letters Patent is:

1. The combination with a driven shaft, a liquid reservoir, a rotating pump communicating with the reservoir, a conduit connecting `the reservoir and pump, a rotating hollow shaft disposed on and closing the conduit over the reservoir, a valve disposed in the conduit, an elongated stem on the valve extending part Way through the rotating hollow shaft, a cross-arm on the free end of the stern protruding through elongated slots in the rotating hollow shaft, arms pivoted to the rotating hollow'shaft and slidably connected to the free ends of the cross-arm,

. weights on the free ends of the arms, contractile springs connecting the arms to the rotating hollow shaft, a bevel-gear securedto'the rotating hollow shaft,'means securing .the rotatingw windmill, a liquid reservoir, a gear pump connecting with the bottom of the reservoir, a conduit connecting with the top of the reservoir and terminating in an enlarged upstanding tubular chamber opened at its upper end and provided with a valve seat at its bottom, a conduit communicating with the top of the pump and extending in communication with the aforesaid chamber above the valve-seat therein, a rotatable hollow shaft resting on and secured to the open upper end of the chamber and having elongated slots therein, a valve operable against the valve-seat and having an elongated stem extending into the hollow shaft, a cross-arm connected to the free end of the valve stem and extending through the aforesaid slots, upwardly directed centrifugal governors pivoted on the rotatingV hollow shaft and connected to the crossarm, means retaining the governors in normal position, and power transmitting means connecting the drive-shaft of the windmill to the rotating hollow-shaft.
